Fix adjust_semi_join to be more cautious about clauseless joins. It was reporting that these were fully indexed (hence cheap), when of course they're the exact opposite of that. I'm not certain if the case would arise in practice, since a clauseless semijoin is hard to produce in SQL, but if it did happen we'd make some dumb decisions.
